I am currently being treated by a neuromuscular dentist for my TMJ disorder. I have had Tens on my facial muscles to relax them, then something called jaw tracking where a magnet was placed inside my bottom lip to find the most comfortable position for the jaw muscles. Impressions were taken and then an orthotic was constucted to wear on my lower teeth 24/7 for a few months to see if it alleviates the symptoms I am having.
The questions I would like to ask are, is it usual for the orthotic to be painful to wear? and if so how long should it take to settle down?
The reason I am asking is because I have had the orthotic for 3 weeks now and am still having problems with it.
When I first started wearing it the orthotic felt very tight but about 4 hours later and my lower teeth started to ache and were extremely sensitive to any pressure. eating was a very painful experience. Wearing it through the night was impossible as it kept waking me up and my hands were tingling in the morning.
I notified my dentist and asked if it needed to be so tight. He said he didn’t really want to make it any looser as it would settle down within a few days and to take Ibuprofen for the pain which I did.
I carried on like this for a week but each time of wearing and the same thing happened. I had to keep removing it for some relief.
I again reported back to my dentist who instructed me to wear it as long as I can through the day but to leave it out while sleeping. It is now a week later and things are not much better. I am starting to feel dispondent about it all and wonder if something is not quite right with the orthotic. When I remove it my lower back teeth are painful to touch and feel very sore where it has been gripping.
How long should it take for the orthotic to feel comfortable? I expected some degree of discomfort during the stage of getting used to it but surely it should be feeling ok by now? I am afraid that by continuing to wear it may cause more harm than good. I have no improvment as yet in the tmj symptoms either. I have paid a great deal of money for this treatment but thought it was worth it to feel well again. Could you give me some advice please.

As both a dentist with 15 yrs experience of making orthotic splints and having worn them myself for many years, a splint should be tight enough to create a stable bite but not painful to wear. If after the first couple of days it is causing discomfort to the extent that you have to leave it out then it needs relieving. Night time wear is usually the most critical as it is during restless sleep that most parfunction (tooth grinding) occurs.

 

The neuromuscular approach is somewhat different to my training however in that I have always found that if the jaw joints are seated correctly and the splint creates harmonious function then the muscles will spontaneously relax (so called 'neuromuscular release')

 

I would always test this with a simple Lucia Jig appliance first to be certain that more complex, protracted and expensive splint treatment will be successful. This Jig is also a good way to relax the muscles to allow one to seat the jaw correctly.

There are many different schools of thought re occlusal problems  (bite problems). Some dentists will even say that TMJ problems are not related to occlusion. 

I personally do not believe in partial coverage splint but rather a flat plane full coverage appliance that should be very comfortable to wear and start to relieve symptoms within a few days. 


I would Advise looking for a dentist from the British society of occlusal studies www.bsos.org.uk. 


It is difficult to comment further without examining you and seeing  the orthotic device . However in my experience partial coverage splints are to be avoided .

TMJ disorders are a very common complaint and have their origin in a whole host of different factors from the coverall of stress or stressful things such as hard work, house moves domestic disharmony etc to occlusal disharmony (uncomfortable bite) due to a high filling new crowns or occasionally an anatomical problem due to the way the jaws are related to each other and hence the way the teeth contact.


As the condition usually has a multitude of factors creating the symptoms the dental and medical profession has created a multitude of cures - all of which can have some merit , from change in diet and simple analgesics, simple to complex 'orthotic' devices (to use the american parlance) to drug regimens and psychological treatments and in extremis surgery. All of the 'cures' have approximately the same success rate and will usually give some relief from the acute symptoms that you may be suffering. No treatment at all will usually have the same statistical success rate in the long term but this does not deal with your immediate problem.


Using a pseudo scientific approach as you describe if carefully thought out and undertaken often has excellent success rates, the appliance should however not be uncomfortable to wear after a day or two and if it is it may be too tight or possibly the bite adjustment on it is inaccurate, as always an answer from a web page can never give you the full facts for your case and is just an overview therefore as you have paid a fee for the treatment and it appears not to be doing what you expect you should approach the provider of the treatment and get some help, if the appliance needs modification or remaking most would feel it reasonable that this should be included in your original fee - although if you have had specific consent for the procedure then it may be worth looking at your contract with the appliance provider.


In summary, TMJ problems are common, they tend to get worse and improve all by themselves, acute symptoms can often be improved by use of an occlusal appliance or orthotic and some like all human problems will sadly never get better at all. It is however unlikely that you will ever be cured of your problems just alleviated of them for the majority of the time with the appropriate help.
